The gulf separating scientists from nonscientists extends to the intellectual world as well. This situation was articulated by C.P. Snow when he called attention to the problem of "two cultures"--one established by literary intellectuals, the other by scientists. In a lecture given at Cambridge University in 1959, he said, "I felt I was moving among two groups--comparable in intelligence, identical in race, not grossly different in social origin, earning about the same incomes, who had almost ceased to communicate at all."
